About multitasking Your BlackBerry® device supports multitasking, which allows you to run more than one application at a time. During a call, for example, you
might want to switch to the calendar application to view your appointments or switch to the contacts application to look up a contact. While
you are playing a song, you might want to switch to the messages application to reply to a message.
There are also shortcuts for most applications that can help you to perform common tasks quickly.
Note:   The more applications that you have running, the more memory and battery power your device uses. To optimize the performance of
your device, try to close applications when you are finished with them.
